Step into a world of daring escapades and dazzling intellect as the enigmatic Prince Rénine (who bears a striking resemblance to a certain gentleman-thief named Arsène Lupin) sweeps the bored but bright Hortense Daniel into a whirlwind of eight perplexing mysteries. Their journey begins with a case hitting close to Hortense's heart, propelling them across the picturesque landscapes of northern France. Together, they navigate intricate webs of deception, outwit cunning criminals, and play Cupid for star-crossed lovers, all while inching closer to recovering a treasure Hortense holds dear.
